In universe, matter is observable in everyday life in
four states: solid, liquid, gas and plasma. There are other states
of mater known to exist only under extreme situations. Matter,
whatever the states, is made of atoms. The states are defined in
terms of inter-atomic distance, atomic arrangement and atomic
ionization in matter. In solid state of matter, the arrangement of
atom-forms different structure of materials. The structure of
materials is the key deciding factor for different kind of
properties, such as thermal, electrical, optical, magnetic,
dielectric etc. In this course we will learn the structure of solid
materials and their different physical properties along with
underlying physics.
